I need to no what parts i need to replace on my mother board there are 2 on the backside and one infrount that are burnt how do i find out the nubers to get the parts
Could you post a picture? Just to indicate, what is burnt.
The 3 pin IC (SOT-223) on the back side is an EH16A.
On the front side the voltage regulator (typically also burnt; 8 pin) is TPS54328. Main reason for dead is a not proper soldered exposed thermal pad on the bottom of the IC.
What else can be burn? The two parallel MOSFETs for power switch. Those are MDU3603 at my Blade 350QX. I think Q500 has the same, but not sure. I do not want to open my Q500 for now. Blade 350QX and Q500 have nearly the same layout.
